Frequent Questions

What types of materials should be used for a rain water collection system?

Provided the rainwater is for non-drinking water purposes, virtually any materials can be used in the collection system. However, if the rainwater will also be used to meet the potable water needs of a home's residents, it is important that the homeowner use care in selecting materials and coatings which will come into contact with the water as it is collected, since some impurities can be picked up by the rainwater as it travels through the collection system.
